Research Abstract

The objective of this study is clarification on mechanisms of fertilization at ocean surface and upwelling of deep sea water by perpetual salt fountain. The possibility on fertilization of ocean was evaluated though the analysis of observation data from satellite. As a result, the increment of chlorophyll concentration was confirmed by line integration of variation of chlorophyll concentration on trajectory of pipe.
